One-Punch Man Wiki

"The Key to His Power" (強さの秘訣, Tsuyosa no Hiketsu, Tonari: 11) is the 11th chapter of the One-Punch Man manga series.


Saitama begins to tell Genos and Carnage Kabuto the secret to his power, revealing that the key is that no matter what, one must see the training through to the end. He then goes on to say, rather seriously, that he became as strong as he is by doing 100 push-ups, 100 sit-ups, 100 squats and 10 kilometers of running every day, he then goes on to give other advice such as eating healthy and never using an air conditioner be it summer or winter to strengthen one's mental fortitude. Saitama then concludes his speech by saying that the true power of humanity is not messing around with evolution, but their ability to change themselves on their own. Genos then gets up, yelling at Saitama, telling him to stop being ridiculous and stating that the training regimen that Saitama had described was standard BOG strength training and isn't even all that hard. Saitama is confused by this, because he told Genos all that he'd done to become strong.

Carnage Kabuto, believing that Saitama was making fun of him, goes berserk and enters Asura Mode. Carnage Kabuto states that while in this form he will go on a rampage for a whole week, destroying town after town until next Saturday. Carnage Kabuto then rushes forward and starts to pummel Saitama, beating him around the room mercilessly. During this barrage of attacks, Saitama realizes that he had mistaken the day and missed the special sale at the store, freaks out and punches Carnage Kabuto's head off, along with most of his torso. Dr. Genus, who witnessed the entire event, decides that evolution isn't the way to change, it is he himself who needs to change.
